Lesi sihloko sizokuqondisa ngezisekelo zezibalo, izindlela ezivame ukusetshenziswa, kanye… Funda kabanzi
Kuyini Izibalo Eziningi? Izibalo Eziningi ziyigatsha lezibalo elihilela ukubuka kanye nokuhlaziywa ngasikhathi sinye kwezinguquko zezibalo ezingaphezu kweyodwa. Umgomo wokuhlaziywa kwezibalo eziningi ukuqonda isakhiwo esiyinkimbinkimbi sedatha nokuthola amaphethini angenakutholakala ngokuhlaziywa okuguquguqukayo okukodwa. Ngokukhula okuqhubekayo kwenani ledatha etholakalayo emikhakheni eyahlukene, izibalo eziningi… Funda kabanzi
I-T-Test ku-Inferential Statistics I-Inferential statistics iyigatsha lezibalo ezisetshenziselwa ukufeza iziphetho mayelana nenani labantu ngokusekelwe kudatha yesampula. Elinye ithuluzi elivame ukusetshenziswa ekuhlaziyweni kwe-inferential yi-t-test. I-t-test iyindlela yezibalo esetshenziselwa ukunquma ukuthi kukhona umehluko omkhulu phakathi kwezindlela zamaqembu amabili noma ukuqhathanisa… Funda kabanzi
Ukuhlaziywa Kwezici Ezibalweni Izibalo ziyigatsha lesayensi elibhekene nokuqoqwa, ukuhlaziywa, ukuchazwa, kanye nokwethulwa kwedatha. Indlela eqinile yezibalo ivumela abacwaningi ukuthi benze iziphetho ezinolwazi nezisebenzayo mayelana nenani labantu kusukela kusampula. Enye indlela ebalulekile kuzibalo ukuhlaziywa kwezici. Lesi sihloko sizoxoxa ngokuthi ukuhlaziywa kwezici kuyini, kungasetshenziswa kanjani, nokuthi kungasetshenziswa kanjani.
Izibalo ekucwaningweni nasekubalweni kwezimali Izibalo ziyigatsha lezibalo elifunda indlela yokuqoqa, ukuhlaziya, ukuhumusha, nokwethula idatha. Ezweni lebhizinisi, ikakhulukazi ekucwaningweni kwezimali kanye nokubalwa kwezimali, izibalo zidlala indima ebalulekile. Ulwazi namakhono ezibalo kuvumela abahloli bezimali kanye nababhali bezimali ukuthi benze ukuhlaziya okujulile futhi benze izinqumo ezingcono… Funda kabanzi
Ifomula Yephesenti Kuzibalo Iphesenti ingumqondo obalulekile kuzibalo, ovame ukusetshenziselwa ukuqonda ukusatshalaliswa kwedatha nokuqhathanisa amanani ngamanye ngaphakathi komongo wesethi yedatha enkulu. Lesi sihloko sizoxoxa ngomqondo wamaphesenti ngokujulile, ukuthi ungawabala kanjani, kanye nokusetshenziswa kwawo okusebenzayo emikhakheni eyahlukahlukene. Ukuqonda Amaphesenti Amaphesenti ayizilinganiso zezibalo ezibonisa… Funda kabanzi
Ukuhlaziywa Kweqembu Ezibalweni Isingeniso Ukuhlaziywa kweqembu kuyindlela ebalulekile ezibalweni ezisetshenziswa ukuhlukanisa isethi yezinto noma idatha ibe ngamaqembu afanayo ngokusekelwe ekufaneni noma ezicini ezabiwe. Ezweni eligcwele idatha enkulu, ukuqonda isakhiwo namaphethini ngaphakathi kwedatha kuyinselele enkulu. Ukuhlaziywa kweqembu kunikeza impendulo yalokhu… Funda kabanzi
Imiqondo Eyisisekelo Yokusabalalisa Imvamisa Ukusatshalaliswa kwemvamisa kuyindlela ebaluleke kakhulu kwizibalo zokuhlela nokuhlaziya idatha. Leli gama libhekisela endleleni amanani edatha ahlukaniswe ngayo ngezigaba noma izikhawu kanye nendlela imvamisa yesigaba ngasinye eqoshwa ngayo. Ngokuhlola imiqondo eyisisekelo yokusatshalaliswa kwemvamisa, singaqonda ukuthi singayichaza kanjani idatha nge… Funda kabanzi
Amasu Okuqoqwa Kwedatha Ezibalweni Izibalo ziyisifundo esibalulekile ekusekeleni ukwenziwa kwezinqumo okuqhutshwa idatha. Ezibalweni, ukuqoqwa kwedatha kudlala indima ebalulekile ngoba ikhwalithi yokuhlaziywa kwezibalo incike kakhulu kwikhwalithi yedatha eqoqwe. Ngakho-ke, amasu okuqoqwa kwedatha abalulekile. Lesi sihloko sizoxoxa ngamasu ahlukahlukene okuqoqwa kwedatha… Funda kabanzi
Izibalo zeSayensi Yezenhlalo Izibalo zidlala indima ebalulekile emikhakheni eyahlukene yokufunda, okuhlanganisa nesayensi yezenhlalo. Njengegatsha lezibalo eligxile ekuqoqweni, ekuhlaziyweni, ekuchazeni, nasekubonisweni kwedatha yezinombolo, izibalo sezibe ithuluzi elibalulekile ocwaningweni, ekuhlolweni kwenqubomgomo, nasekuthathweni kwezinqumo. Kusayensi yezenhlalo, izibalo zivumela abacwaningi ukuqonda izenzakalo zomphakathi, ukuziphatha kwabantu, kanye nesakhiwo… Funda kabanzi
